Flashcards in Photosynthesis Deck (37):
1

All life on Earth depends on the flow of _____

Light energy

2

The source of energy in photosynthesis is from the _____

Sun

3

Autotrophs:

Organisms that can make their own food

4

Heterotrophs:

Organisms that cannot make own food

5

How do autotrophs get food

Use light energy from the sun to produce food in the form of glucose/sugar

6

Examples of autotrophs

Green plants, some bacteria, some protists

7

Examples of heterotrophs

All animals, fungi

8

ADP:

Adenosine diphosphate

9

ATP:

Adenosine triphosphate

10

What is significance of the third phosphate in ATP

To store excess energy

11

Three parts of ADP/ATP

Adenine, ribose, phosphate groups

12

Cellular activities that would require the energy of ATP

Active transport, cell division, DNA synthesis, spindle formation for DNA replication

13

Why is it important for ATP to become ADP

Use extra phosphate group as a source of energy

14

How does ATP turn into ADP

The phosphate group breaks off

15

How does ADP become ATP

Adds a phosphate group - energy comes from glucose

16

What is equation for photosynthesis

6CO2 + 6H20 yields C6H12O6 + 6O2

17

How does chlorophyll make a plant appear green

The chlorophyll captures red and blue lights and then reflects green wavelengths

18

What plant structures control the passage of H2O out of the cell and CO2 into the cell

The stomata

19

Is carbon dioxide produced during photosynthesis

No

20

Are all parts of the plant able to carry out photosynthesis

No

21

Life on earth is dependent on photosynthesis for what two things

Oxygen and glucose

22

Why do autotrophs depend on heterotrophs

Carbon dioxide

23

Where does the plant take in water

Through roots

24

How does the plant get carbon dioxide

Through the stoma of the stomata

25

Name of waxy layer on leaf that prevents water loss

Cuticle

26

What is any substance that absorbs light called

Pigment

27

Name of cells in leaf that are primary photosynthetic layer of the leaf

Pallisade

28

Name of middle portion of leaf

Mesophyll

29

Pores on underside of the cell are called

Stoma

30

What carries water to the leaves from the roots

Xylem

31

What carries food out of the cell to all other parts of the plant

Phloem

32

Plants absorb the sun's energy with _____

Light absorbing pigments

33

Chlorophyll a:

Blue-green

34

Chlorophyll b:

Yellow-green

35

What parts of the cell contain chloroplasts

Pallisades and spongy cells

36

What are the guard cells

Stomata

37

Where are the xylem and phloem

In vascular bundles
